Abstract

PROBLEM TO BE SOLVED: To eliminate irregularity in illumination over the entire pilot lamp light emission surface in mutually continuous directions by arranging a diffusion sheet which makes an LED illuminate uniformly over the entire LED light emission surface between the LED and an LED cover. SOLUTION: The diffusion sheet 13 is mounted on a printed board 12 in the front of the LED 11 so that the entire LED light emission surface 11a of the LED 11 illuminates uniformly. In this constitution, the light emitted by the LED 11 impinges on the diffusion sheet 13 to cause surface light emission along the surface of this diffusion sheet 13 and then the light emitted by the LED 11 is uniformly diffused and projected to prevent the pilot lamp light emission surface 16 from having irregularity in illumination. Consequently, when the LED 11 illuminates, the pilot lamp light emission surface 16 of the LED cover 14 illuminates and is continuous to the front and flank of a case main body 15, so the illumination of the pilot lamp can be confirmed from places over a wide range.

【発明の属する技術分野】
本発明は、ＬＥＤを用いて、互いに連続した複数方向の表示灯発光面を有するナースコール用廊下灯に関する。
【０００２】
【従来の技術】
従来、ＬＥＤによる表示灯装置は、図３に示すように、プリント基板３２に複数個のＬＥＤ３１を実装し、このＬＥＤ３１のＬＥＤ発光面３３の正面延長上に乳白色材料を成形して形成されたＬＥＤカバー３４を配置すべく本体ケース３５に収容固定して構成していた。そして、ＬＥＤカバー３４は、互いに連続した複数方向（この場合、本体ケース３５に対して前方および側方）の表示灯発光面３６、３７を有して構成されている。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記従来のＬＥＤによる表示灯装置は、ＬＥＤ３１より発した光を、乳白色のＬＥＤカバー３４の表示灯発光面３６、３７のみからの拡散のみに依存しており、ＬＥＤ３１が発する光には、方向性があるために、外部へ射光される光が表示灯発光面３６、３７のいずれか一方のみより射光されることになって、他方の表示灯発光面に光りムラが生じてしまい、このような表示灯装置を用いた電気設備機器例えばナースコール用廊下灯においては、射光方向位置に移動しなければ、表示確認ができないという不便を強いていた。
【０００４】
そこで、本発明は、互いに連続した複数方向の表示灯発光面全体に、光りムラが発生しないナースコール用廊下灯を提供することを目的としている。
【０００５】
【課題を解決するための手段】
本発明は、上記目的に鑑み、ＬＥＤとＬＥＤカバーとの間に、前記ＬＥＤのＬＥＤ発光面全体を均一に発光させる拡散シートを配置し、ＬＥＤカバーを、廊下における取り付け壁面に取り付けられるケース本体の左右両端部の正面および側面にかけてそれぞれ配置して構成した、ナースコール用廊下灯であることを特徴としている。
【０００６】
本発明によれば、拡散シートによって、ＬＥＤが発光する光を、ＬＥＤ発光面全体に均一に拡散して、ＬＥＤカバーにおける複数面の表示灯発光面全体から射光させて、広範囲の場所より表示灯の認識が可能となる。
【０００７】
【発明の実施の形態】
請求項１に記載の本発明は、プリント基板と、このプリント基板に実装されたＬＥＤと、このＬＥＤのＬＥＤ発光面全体を均一に発光させるよう配置した拡散シートと、プリント基板とＬＥＤと拡散シートとを収容し廊下における取り付け壁面に取り付けられるケース本体と、ケース本体の左右両端部における正面および側面にかけてそれぞれ配置され、互いに連続した複数方向の表示灯発光面を形成するＬＥＤカバーとを有し、拡散シートは、ＬＥＤとＬＥＤカバーとの間に配置されることを特徴とするナースコール用廊下灯である。
【００１０】
これによれば、拡散シートによって、ＬＥＤが発する光を、ＬＥＤ発光面全体に均一に拡散して、ＬＥＤカバーにおける複数面の表示灯発光面全体から射光させて、広範囲の場所より表示灯の認識が可能となって、表示灯の点灯により行う作業を迅速かつ確実に行うことができる。
【００１１】
以下、本発明の実施の形態を図面を参照して詳述する。
【００１２】
（実施の形態１）
図１は、本発明による実施の形態におけるナースコール用廊下灯を示す斜視図、図２は、図１のＩＩ−ＩＩ断面図である。
【００１３】
図において、ＬＥＤ１１、ＬＥＤ１１を実装するプリント基板１２、ＬＥＤ１１のＬＥＤ発光面１１ａ全体を均一に発光させるようＬＥＤ１１の正面に配置するようにプリント基板１２に装着された拡散シート１３、およびこれらＬＥＤ１１、プリント基板１２および拡散シート１３を収容するケース本体１５、このケース本体１５の正面および側面にかけて配置され、拡散シート１３の正面に位置して互いに連続した複数方向の表示灯発光面１６を有するＬＥＤカバー１４を有して表示灯装置１０を構成している。
【００１４】
そして、この表示灯装置１０は、ケース本体１５を取付け壁面２６に取り付けることによって、ナースコール用廊下灯を構成している。
【００１５】
上記構成において、ＬＥＤ１１で発した光は、拡散シート１３にあたり、この拡散シート１３の面に沿って面発光し、ＬＥＤカバー１４の表示灯発光面１６全体から、ＬＥＤ１１で発した光が均一に拡散射光されることになって、従来のような表示灯発光面の光りムラ発生を防止することができる。
【００１６】
この結果、ＬＥＤ１１が点灯すると、ＬＥＤカバー１４の表示灯発光面１６の表面が発光するが、このＬＥＤカバー１４の表示灯発光面１６は、ケース本体１５の正面および側面に連続しているために、図１の矢印方向から表示灯装置１０の点灯が確認できる。したがって、表示灯装置１０を、取り付け壁面２６例えば病院等の廊下における取り付け壁面に設置するナースコール用廊下灯として用いれば、ナースは廊下のどちらの方向からも点灯を確認することができ、表示灯の点灯により行う作業を迅速かつ確実に行うことができる。
【００１７】
【発明の効果】
本発明によれば、ＬＥＤの正面に配置した拡散シートによって、ＬＥＤが発する光を、ＬＥＤ発光面全体に均一に拡散して、ＬＥＤカバーにおける複数面の表示灯発光面全体から射光させて、広範囲の場所より表示灯点灯の認識が可能となって、表示灯の点灯により行う作業を迅速かつ確実に行うことができる。
